Adaptec 6805TQ maxCache RAID controller

Specifications:

Adaptec maxCache 2.0 Storage Controllers– Evolved Performance
First generation maxCache offered significant performance gains for read-intensive applications, delivering up to 11x performance improvement in 100% random read workloads. Using SSDs to cache copies of frequently accessed – or ‘hot’ – data, maxCache exploits the performance capabilities of SSDs to access the read data from the SSD rather than spinning media. Read caching is improved with maxCache 2.0, with additional optimizations to the learned-path algorithm delivering an increase in overall IOPs performance to 13x for read-intensive environments.

To deliver the advanced performance capabilities of SSD caching to a broader set of application workloads, maxCache 2.0 evolves to offer caching of write data as well. By caching writes to the SSDs, maxCache 2.0 leverages the performance and latency capabilities of SSD technology for workloads with reads and writes

Closer Look:

The noticeable points on the 6805TQ card are the second layer circuit board that is sandwiching a large portion of the circuitry of the card. Also the locations where the cables are connected to the card are located in the middle of the card. The 6805TQ doesn’t have a sticker warning that it requires sufficient air-flow for cooling like the 6805E. The 6805TQ needs only standard computer case airflow, so you do not need to breakout the nitrogen cooling system.

The cables are the same as the 6805E card review. These two cable branch out to four HDD each, for a total of eight supported HDDs.
